### Full prompt
```text
Vertical travel poster composition, 4:5 aspect ratio, featuring a highly detailed isometric miniature architectural diorama of [Barcelona], Spain, set upon a square dark-wood-edged base against a clean off-white background with generous negative space at the top.

Typography:
At top center, elegant dark charcoal travel poster lettering displays small spaced uppercase "CATALUNYA", followed by a very large, tall condensed uppercase headline "[BARCELONA]", and below it small spaced uppercase "SPAIN".

City Layout and Landmarks:
A dense Eixample-style grid of square blocks with octagonal corners, orange terracotta rooftops, pale stone facades, tree-lined avenues, and tiny vehicles. Incorporate 6 prominent landmark zones: 1) the ornate multi-spire Sagrada Família basilica near the center, 2) a lush green park zone resembling Parc de la Ciutadella on the upper left, 3) a rounded blue-and-red football stadium on the right, 4) a bullet-shaped glass skyscraper resembling Torre Glòries on the left, 5) a sail-shaped hotel tower on a coastal spit at the front center-left, and 6) a beachfront marina district along the front and right edges.

Waterfront:
Deep turquoise Mediterranean sea borders the front edge of the base, featuring harbor docks, rows of tiny white yachts in the marina, a curved sandy beach, and miniature sailboats dotting the water.

Style and Lighting:
3D miniature architectural model photography, three-quarter isometric perspective, warm natural daylight casting crisp soft shadows, saturated natural colors, polished tabletop craftsmanship, tilt-shift depth of field.

Constraints: Clean legible typography, no people in close-up, no extraneous map labels, no watermarks, no borders.
